Question
Chapter 45, Problem 13TYU
Summary Introduction
To determine: The effects of significant reduction of macrophages in the body.
Introduction: A complex network of cells, tissues, and organs that work collectively to protect the body and fight against the pathogens or foreign substances is called the immune system. Immune cells are the cells that actively participate in the defense mechanism initiated by the immune systems. One such major type of immune cells is lymphocytes.
Summary Introduction
To determine: Whether a significant decrease of macrophage or of memory B cells would have a greater effect on the immune system.

A. identity self vs. non-self
B. provide a physical barrier to infection
C. initiate inflammation
D. suppress proliferation
E. call for help from the adaptive immune system
F. circulate fluids through the lymphatic system
Decreased immunity is a symptom of HIV/AIDS. This is caused by which of the following?
Select one:
a. HIV destroys antigens. This decreases the possibility of recognizing pathogens in the future.
b. HIV destroys memory T cells. If the body is infected again, there is no antibodies to fight an infection.
c. HIV attacks the macrophages. Pathogens cannot be destroyed once they enter the body.
d. HIV attacks the helper T cells. This allows pathogen cells to enter the body unnoticed.
